To all whom it may concern..-

Be it known that I, EDWARD O. EA Is, a

citizen of the United States, residingat ".lo- .ledo, Lucas county,Ohio, have invented-certain new and useful Improvements in :Metal- 'li'cGrain-Storage Buildings,'of which'the fol lowing is a specification.-

In the storage of grain in buildings in which the walls and bins areconstructed of sheet is exposed to atemperature lower than that metal,the following difficulties are encountered: First, when a bin is filledwith grain and one or more of its walls is an outside wall,

or a partition wall adjoining an empty bin, thewallthus subjected tostrai-n from one side only' will become distorted,'unless themetal isveryheavy, which entails undue weight and expense in construction;second, when the exterior of the metal wall of abin within the bin,moisture will be condensedupon the inner surface of the exposed wall,and the contained grain next to the chilled surface will become wet anddamaged. I

My invention relates to and its object is toprovide a method ofconstruction for metallic grain storage buildings which shall overcomethe difiiculties above pointed out. 1 I attain these objects bymeans' ofthe construction and arrangement of parts hereinafter de 30 scribed, andshown and illust'rateddn, the accompanying drawings, made part hereof,in which V Figure 1, isa plan section of a sheet metal bin constructedaccording to my method; Fig.

- as shown in Figr 1, .though I doQnot limit my invention to this formof bin; In the drawings, the walls of the building and of the binssecured in close conjunction at their vertical edges, bymeans of boltsor rivets, as at b b,

v and curved away from each other so that in horizontal section the twosheets or shells,

present two equal arcs of a circle, reversed to 7 each other and havinga common chord. The

sheets a are held rigidly in place and'secure against spreadingor-collapse by means of braces,c o, securely bolted or'riveted to andbetween'the sheets a. In the angles .of the walls or bins are verticalangle-irons d columns built up of angle-irons and-inclosing sectors, e ee' and to projecting lips or flanges of these angle-irons or columns thevertical edgesof the walls, a, are secured as above indicated. Thesheets a a may be corrugated or fluted to give them additional strengthand rig idity, as in Fig, 3. The interiorsheets'of I the exterior wallsmay be finely perforated,

as shown in Figs. 2 and 3, so that the temperature of the air spacebetween the double walls and thegrain next the inner wall shall be aboutthesame, thuspreventing condensation on the inside sheet even whenmoisture is condensed on the interior of the'ontside sheet. 1 I

The advantages of the.construc'tion here shown are, first, the greatstrength of the walls, both under tension and'com-pression, inproportion to'the weight of metal used; second, the spaces between thecurved walls (which may be .either for dead air, or be packed withmineral wool, or other non-conducting niater ial) tend to prevent, bysudden changes of temperature, condensation and injury to ;the contentsof the bins, as when the exterior walls are subjected to an extremechange of weather, or -when a bin contains warm grain and an adjoiningbin is then filled with cold grainr What I claim as my invention, anddesire I to secure by Letters Patent, is'- 1'. A metallic grain storagebuilding, having the walls and partitions thereof composed of oppositelycurved sheets of metal suitably secured together at their verticalmeeting edges, substantially as shown and described, for the purposespecified.

2. A metallic grain storage building, having the walls and partitionsthereof consisting of oppositely curved sheets of metal suitably securedto and in combination with vertical columns or angle-irons, in theangles of said building or the bins thereof, substantially as shown anddescribed, for the purpose spool-- fied.

3. A metallic grain storage building, having the bins having wallscomposed of oppositely curved plates meeting at their vertical edges,sitely curved sheets of metal suitably secured IO in combination withcolumns or angle-irons together at their vertical meeting edges, the inthe angles of said bins, and braces in the inner wall being perforated,substantially as spaces between said curved walls rigidly seshown anddescribed, for the purpose specicured to and connecting said walls,substanfied.

tially as shown and described, for the pur- EDWARDO. FALLIS. posespecified. \Vitnesses:
